[Diy_efi] Venturi effect crankcase breather

[don.broadus at exeloncorp.com]

Moroso calls there system the Pan Vac. Your idea will work but you must put
a anti back fire valve between the exhaust and valve cover breather. Also
the valve cover gaskets must be leak free and all breathers be sealed for
the system to work. Improved ring seal.. maybe
3-5 HP but the exhaust velocity must be high to pull a good vac. =20

Hi Guys,

Apologies for the slightly non efi topic.

Has anyone tried plumbing the rocker cover engine breather hose into a "T"
piece plumbed into the exhaust system after the turbos?

Any reason why it would not release a few GG's?

Thanks

Hugh

There's a few PCB's stocked.

(I guess you don't want a fully assembled board?).
Postal address is important. I suggest 2 solder-protected boards
(3+11*2 =3D 25 Euro with airmail shipping), since
 you might want to build a 2nd unit later to have a backup.
Also the L293NE stepper driver and MC34151P FETdriver chips are
cheap (5 and 1 Euro respectively), but you might find it frustrating
to get them in small quantities. (better spend your energy elsewhere).
But if you'll get AAron's kit, it contains these.

2.5 bar ported MAP sensor also available in limited quantity (23Euro).
